Project Reality Forums

Well, I think the entire BF2 series is totally lacking in the way of chemical/biological threats. So, to begin, I'm going to try to make a scuba tank that is full of some harmful gas. The player will walk around with it, when they are about to throw it, they will turn the nozzle on the top, and finally, they will throw the tank (a short distance obviously), and the tank will then be laying on its side pumping gas into the air. Obviously, you'll be needing a gas mask to use one of these. I've tried modeling it just now, this is my first real model (besides like a box) so don't kill me please.


Obviously I still have a lot of work to do, but just let me know what you think of the model and the idea of chemical/biological threats in PR.

Nice Idea , though instead of opening the valve and throwing it, how about making it in to a IED type weapon such as a rigged chlorine tank with more throwing range

Model-wise, you don't really need that many segment/vertices on the purple cylinder (nozzle?). You could just lower # of segments on the primitive property tab to 1 and replace the cylinder or you can target wield/select wield the extra vertices.

original: yes but if it has less polys than most weapons that we have, i don't care =D the better looking a cylynder the better i say!

Edit: ah i see now what you're saying... he has it in segments with wasted polys....

though it might help with making it round a little more i don't know.. depends on how he used it

This would make a nice Militia/Insurgent weapon. Keep it away from the MEC, they are an Islamic conventional army, with all the morals and peaceful values thereof.

Good work!

Im not feeling the chem/bio weapon, perhaps something that Heavy_Z suggested?

I have to disagree. PR takes place in what amounts to World War III, and I'm sure that at least one faction would come to such drastic measures to survive. The most likely factions to do this, of course, are the Insurgents and Militia.

Actually, I was going to make two versions. The first one, which I'm working on now, will be the one that you just place/throw on the ground while you're wearing your gas mask and then run away. The second version will be more like an IED with remote detonation. I just wanted to work on step at time, so I figured the throwable tank would be easier.

As far as the vertices and model go, I have no idea. I just used the cylinder and chamberfx cylinder (something like that) object creators. I'll look into it, less polies the less lag right?

Right, less polys are one of the things that keeps done the lag. It's always good to cut down unnecessary polys/verts that could be used otherwise for more details on the necessary things.

don't know if you've worked on it a little more yet but the weapon doesn't really look like a gas tank ATM, I'd suggest getting some reference pictures of real chemical tanks and modify the current model a bit, it'd give a more realistic appearance.

For example you could try something like this:

As far as the realism goes, I think it's perfectly reasonable for the insurgents to use chemical weapons such as chlorine bombs considering they've already used them in Iraq and ideally they're pretty easy to make:

though how large is this "chemical bomb"? Is it size of a fire extinguisher etc.?

Cool, I actually have seen gas tanks like the one I made (a couple pictures of google images); however, those ones in the middle of your image don't even have a top, how does one let the gas out on something like that?
Most of my influences came from SCUBA tanks because I work with them a lot.
Ok, I spent today remodeling it and trying to UVW map it (I just have to do some little details on the texture like the nozzle hole, chemical warning stickers, etc.)
I'll probably go ahead and make this one an IED because it does sound kind of dumb to have some guy walk around with a tank of compressed air just so he can throw it.
Anyway:

Now I just have 2 of those extended primary cylinders (each with 8 faces, that's as few as I can go before they begin to look too much like polygons)
I also tried to add rust as you can see, but it looks like a failure of sorts. I'm going to try to shink the rust then add it back to the texture. (BTW, all thanks to marcoelnk for his UVW tutorial on BFEditor)

Just wondering- will the effect like the cloud look like the BFSF Tear Gas?

I'd prefer it to be the stereotypical green gas cloud so everyone doesn't complained when the smoke grenades own them
1 small problem I see with this weapon,no kill ownership(unless you make the projectile have a large collisionmesh)and tha people will bleed if they get gassed,they might in Rl but I'm not sure about it

I'm thinking of using an effect similiar to the tear gas. Obviously, the effect will be much more transperant because the tank is filled with chlorine gas (thus a yellow-green gas color will be used). Also, the area of affect will be much larger because you are blowing up an airborne toxin (ie. sending it at an extremely fast rate into the surrounding air).
Overall, I'm thinking of the weapon having a small explosion (like .756 grenade size) explosion and then the larger plume of gas. The point of the larger plume of gas, besides general realism, is to enforce the idea that if it is even possible that the enemy has chemical/biological weapons soldiers should always be wearing their gas mask. Also, I want to make the plume larger so that you can't just quickly run away and be all fine without even using your mask. I'm hoping the damage will be something like -2 hitpoints per second of exposure. I might also have some sort of disorienating effect with the gas. I'm going to research the effects of chlorine a bit more. I'm pretty much finished with the skin:

The model uses a 2048x2048 size image, but for some reason it always look bad in 3ds max. I actually took the time to find the correct NFPA 704 (those things you see all over chemicals and in labs) warnings for Chlorine gas and that's what I used on the side of the tank.

In the viewport, the texture will look strange, but to look a little better, go to: Customize>Preferences>Viewports>Configure Driver and put your configs like this:


I don't know for what each config in this window is useful for, but for me it's ok at this way.


Ohhh, and press F9 to make a render. Viewport screens will always be in less quality than a render!


Cheers!

It sort of worked, but the image isn't good enough to see the warning decal and the hole (not model, just texture) where the gas escapes from. It's ok though.
Well, I did the hierarchy and messed with the model some more, but when I try to export I get no products.

Note that I've done nothing besides map editor, uvw mapping, uvw unwrap and the hierarchy itself. Anyone know why it would not be exporting?

Thanks.

Help?

- "geom_1p" should be "geom0_1p" or just "geom0".
- "lod1" under the geom1 should be "lod0".
- In both cases there should be two underscores before "GenericFirearm", not one. Otherwise it will export as a SimpleObject rather than a weapon.

Thanks

Help me again - I have the weapon temporarily as part of the ambusher kit and when I spawn out with the kit I get this error:

How do I fix this?

No idea, but when it comes to effects:

Gases dont' explode out of containment tanks unless the tank is ruptured. No explosion at all just by opening the valve and letting it out.

Depending on the gas it'll either be heavier than air or lighter than air. Lighter gases will spread out rapidly and diffuse easily in open spaces; gases heavier than air will stay low to the ground and will be linger for longer.

However, with any form of wind around they're not an effective weapon - which is why they weren't used in conventional wars beyond WW2. Both sides quickly learnt in WW1 that you had to be damn sure the wind was going to be staying in the same direction for a long time to stop it blowing back onto friendly troops.

So to model the effect of chlorine best you should have a pale yellowy green 'smoke' that hugs the ground, spreads fairly slowly to a maximum size and then diffuses fairly quickly.


I can give you a fairly graphic description of what it's like to be gassed by chlorine, having been involved in an accident with it 4 years ago in a university chemistry lab

I think that a 'biological' weapon (plaque/cholera ...etc) would be more appropriate,no?
I can imagine animation for it: an insurgent shaking it,looking throe the bottle on the light,sniffing it (well maybe not sniffing)
Anyway great idea,best of luck EOD !
